只需按
if(isset($_POST['submit'])){
  //yada yada

在进行选择之前，只需执行以下操作
if(isset($_POST['submit'])){
  //yada yada

在执行选择之前，您还可以使用javascript刷新页面：
<script type="text/javascript">
    document.location = "URL"
</script>


document.location=“URL”
您还可以使用javascript刷新页面：
<script type="text/javascript">

当您的代码现在运行时，通过F5刷新的人将再次插入相同的值。。。P-R-G避免了这个问题。
